I found this somewhat interesting...
As of 2007, two-thirds of adult Internet users shop online, compared with just half a year earlier. Most spend $100 or less a month, and two-thirds of online shoppers have reduced buying at brick-and-mortar stores.
Sixty-one percent of adult Americans said they were very or extremely concerned about the privacy of personal information when buying online, an increase from 47 percent in 2006. Before last year, that figure had largely been dropping since 2001.
Nonetheless, concerns about credit card security have largely stabilized, with 57 percent very or extremely concerned last year. It was 53 percent in 2006, a difference within the survey's margin of sampling error of 3 percentage points in either direction.
